Problems solved by technology

[0002] In the field of construction, steel bars are an indispensable building material, and with the rapid development of the economy, the demand for steel bars in high-rise buildings has been greatly increased, and there are also high requirements for the quality of steel bars, and in the actual use process In the field, the steel bars used on site will be reprocessed according to the actual situation, that is, re-cut or lengthened. In the existing technology, the method of lengthening the steel bars is mostly manual welding, and the steel bars are connected and welded using welded joints. Manual hand support is required. During the processing, since the two ends are in the suspended position, the welding deviation or inclination may occur. After welding, the steel bars on both sides are not on the same level, which will cause subsequent use. Failure to meet the standard will affect the quality of the building. Although some welding devices are equipped with mounting devices on both sides, due to the long length of steel bars, the mounting devices installed on the device are relatively long and occupy a large space, which is very inconvenient during use and affects Efficiency in use; therefore, it is very necessary to provide a steel bar positioning welding device with good positioning effect, convenient welding and simple operation
